“…In the experiment, ten leaf-cutting ants were allocated, five soldiers and five workers along with a solid diet, in glass vials, sealed with voil, for air passage. To prepare the diet, three grams of dextrose, one grams of food agar, and 100 milliliters of distilled water were used as recommended by Jung et al (2013).…”

Currently, few active principles are authorized by the forest certification for the control of insect pests, with which it is necessary to develop new products, mainly aiming at lower environmental impact. The plants are able to develop substances called secondary metabolites, widely studied as an alternative form of pest control. Thus, the objective of this study was to evaluate the insecticidal potential of two Musa acuminata extracts, on the control of Atta sexdens rubropilosa. The extracts were obtained from the pseudostem of M. acuminata, which underwent drying and milling, producing two extracts: ethanolic (A1) and hydroethanolic rotaevaporate (A2) extract. For the analysis of the bioactivity of the extracts, a topical application of one milliliter of each extract on the ants was carried out, with the aid of spray, in the concentrations of: 2, 6, 10, 14, 18, and 20%, with distilled water (witness) applied to the test, analyzing the mortality and LC 50 , in different evaluation periods. At 24 hours the mortality of 90% at the concentration of 20% for the A1 extract was observed. From the 10% concentration there was 100% mortality in this same period for the A2 extract, and at 48 hours the 2% concentration caused 100% mortality. In the LC 50 analysis for 24 hours values of 7.94 and 1.09% were obtained for ethanolic extract and rotavaporated ethanolic extract respectively. And the LC 50 presented a decrease in values after 48 hours for the ethanolic extract presented value of 2.29%. Thus, it can be concluded that the A2 extract is the most efficient, since it allows the lower consumption of extract in the dilution for later application, due to the presence of insecticidal potential in low concentration.

“…Although pyrantharine derivatives have been reported with a potential bioactive effect on arthropods, research on their insecticidal action is still scarce. JUNG et al (2013), in their work, evaluated the insecticidal activity of the Bordeaux syrup tree, in the concentration of alcoholic extract to 10%, noting a significant effect on the mortality of Atta laevigata Smith of 84.6% when compared with the control. SOUZA et al (2008) evaluated the bioprospection of insecticidal substances native to the state of Mato Grosso do Sul, Brazil, analyzing the insecticidal effect of 10% Bordeaux syrup extract on adults of the weevil (Sitophilus zeamais), observing that on the fifth and tenth day after application of treatment there was mortality of adults around 20 and 30%, respectively.…”

Natural products extracted from plants have always played an important role in the discovery of bioactive substances. This work carried out a review of the literature on the bioactive activities of Eugenia uniflora L. (Surinam cherries), as a potential plant in the various uses, be it medicinal, antimicrobial, antioxidant, insecticide and protective. In the literature, studies were found to confirm the antibacterial activity of E. uniflora leaves extract on Streptococcus, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The presence of antioxidant compounds as total phenolics, such as anthocyanins and flavonoids, induction in the protection of plants by phytoalexins, as well as insecticidal and anthelmintic effects by the use of the extract of the E. uniflora tree. Although these different potential biotics of E. uniflora have already been reported, further studies are still needed on the use of natural products extracted from E. uniflora for employment for different purposes.

“…Eugenia uniflora L. (Myrtaceae) is a species with a wide distribution in Brazil; its extracts and essential oils have revealed insecticidal activity against Atta laevigata Smith and Sitophilus zeamais Motschulsky (COUTINHO et al, 2010;JUNG et al, 2013) as well as acaricidal activity against Tetranychus urticae Koch (NEVES et al, 2009).…”

Tetranychus evansi Baker & Pritchard and Tetranychus urticae Koch (Acari: Tetranychiade) are important mites for the economy of many countries. Populations from these species have presented resistance to acaricides of different chemical groups, thus demanding new products with an acaricidal effect. Essential oils have been investigated. The chemical composition and acaricidal effect of the Eugenia uniflora L. (Myrtaceae) essential oil were investigated. The essential oil was extracted by hydro-distillation and the chemical composition was identified by Gas Chromatography coupled to Mass Spectrometry (GC/MS). Repellence, fumigation and residual effect tests were performed. The essential oil presented the sesquiterpenes selin-1,3,7(11)-trien-8-one and selin-1,3,7(11)-trien-8-one epoxide. Repellence occurred against T. urticae and T. evansi. Oil vapors provoked 100% T. evansi mortality at all concentrations and time intervals tested with significant mortalities being observed against T. urticae after 48 h. Tetranychus evansi mortalities greater than 80% due to a residual effect were recorded after 24 h, whereas no significant mortality was observed for T. urticae.
